Our home is very unique with floor to almost the ceiling arched windows. If it wasn't for the owner (Gene) of Window World going above and beyond to get our very unique windows made at an affordable price, we would not have been able to enjoy our new beautiful windows we have had for about 4 years. All the new vinyl windows have withstood the very hot summer sun in Ramona without any problems. Wow, they open and close so well with a better design that Gene 👏 thought of to do. We now have 3 windows stacked on top of each other in each of the large and small window openings with caulking and frames, so that the middle window will open wide with a screen to get a nice breeze in the cooler nights of our Ramona summers ☀️. Art and Jason were great to come out today on time and use their repair skills on the top arch part of one window. They were professional, polite, and thorough. You can't go wrong with this A+ company and their superb windows. The price, quality, beauty, care, service, and outstanding lifetime transferable warranty is the best we could find. Score!

We had Art from Window World San Diego out for warranty service and he was excellent. He is genuinely friendly, clearly explained what to expect, and stayed in touch on timing so there were no surprises. Work was done efficiently and professionally, and he made the whole process easy. Highly recommend asking for Art!

I had my front entry door and a window latch serviced by Art. He was outstanding and provided great customer service. Very knowledgeable so the work was completed in minutes. My entry door opens and close with ease. The window latch was replaced and functions like new.

I am glad I talked to my coworker before I had my windows and sliding door installation. The Window World Installation team was so easy to deal with. Whatever they promised me then that’s what i got with no hassle or disappointment. Will, Chuck, Carlos & Mario demonstrated an outstanding work ethics, professional and best of all their excellent end product. I had a very busy working schedule and they were very flexible in accommodating it. I loved my new windows and especially my sliding door. Amazing!!!
Thank you to all 4 of you for your amazing workmanship!
I will provide photos and update once the stucco team completed all the miscellaneous work for my sliding door.
I promised to provide updates after everything are done so here it is. I am happy with everything. I am only posting a few windows and a sliding door.
